WESTFORD, Mass.—(BUSINESS WIRE)—Dec. 5, 2005—
MatrixOne, Inc. (NASDAQ:
MONE), a leading provider of
collaborative product lifecycle management (PLM) solutions for the
value chain(TM), today announced that The Carraro Group, headquartered
in Padua, Italy, has selected MatrixOne as its PLM platform. The
Carraro Group designs, manufactures and sells drive train systems for
earthmoving equipment, tractors, materials handling equipment, light

escalators. The MatrixOne solution will enable Carraro to manage all
aspects of the product lifecycle process, including product
requirements, development of the product within the design office,
creation and management of the design bills of materials (BOM) and
integration with the ERP and CAD systems currently installed.

Mario Carraro, the Group's President and CEO, said "the innovation
we achieve through the use of PLM allows us to protect our competitive
advantage by anticipating our customers' needs and providing high
value-added products and services. For this reason, we are happy to
have reached an agreement with MatrixOne to implement a PLM solution
that will allow us to significantly improve the product development
processes and effectively support the group's strategic and business
objectives."

"As part of Carraro's overall growth strategy, the adoption of a
PLM system allows us, first of all, to transform the management of
complexity into a potential competitive advantage," said Marco
Tecchio, the Carraro Group's Technical Director. "Secondly, the
innovation will be placed at the center of all processes; integrating
the fundamental aspects of product development from strategic
marketing to post-sale services and from technical skills to system
integration. This will allow us to strengthen the market's perception
of Carraro as a reliable and competitive partner for developing
successful and technologically advanced solutions."

According to Luigi Salerno, MatrixOne's Regional Sales Director
for Northern and Southern Europe, "the agreement to implement the PLM
project at Carraro is particularly satisfying because the Carraro
Group is considered a leading example, both in Italy and
internationally, of a company with global success that has focused on
innovation as a strategic objective."
